  4. Chapter 1 Movie Special Effects Section 6 Metals and Nonmetals (pp.60-67) Atlantic Coast High School

  5. What do you see? (WDYS)

  6. What do you think? (WDYT) • Why are frying pans made of metal and baking dishes often made of glass or ceramic? • Could a baking dish be made of metal? Could a frying pan be made of glass or ceramic?

  7. Investigate • Metals vs. nonmetals

  8. Data Table

  9. C1S6 Chem Talk Pages 63-64 Read the section. • Make three columns and list the properties of metals,nonmetals and metalloids.

  10. Chem Talk Properties of Metals • Metals are good conductors of heat and electricity • Metals are malleable • Metals are ductile • Metals have high tensile strength • Metals have luster

  11. Electron Sea Model

  12. Chem Talk Mercury, Hg, is the only metal that exists as a liquid at room temperature Copper, Cu, is a relatively soft metal, and a very good electrical conductor.

  13. Chem Talk Properties of Metalloids • They have properties of both metals and nonmetals. • Metalloids are more brittle than metals, less brittle than most nonmetallic solids • Metalloids are semiconductors of electricity • Some metalloids possess metallic luster

  14. Chem Talk Alloys An alloy is a substance composed of two or more metals, or of a metal or metals with a nonmetal, and still maintain the characteristic properties of metal • Common Alloys • Bronze - probably the first intentionally created alloy • Steel • Brass • Sterling silver (92.5% silver, the rest usually copper) • 10K (or 12K, or 14K, or anything under 24K) gold • The "nickel" nickels are made of (mostly copper)

  15. Chem Talk Nonmetals • Nonmetals are poor conductors of heat and electricity • Nonmetals tend to be brittle • Many nonmetals are gases at room temperature We will focus on nonmetals later… Carbon, the graphite in “pencil lead” is a great example of a nonmetallic element.

  16. What did I miss in this section?

  17. Checking Up (CUQ) p 64 1. Why is it important to prevent the oxidation of metals used in construction? 2. Explain the meaning of an alloy. 3. Why are alloys used? 2 column format!!! Question on left, answer on right

  18. What do you think now?(WDYTN) • Using what you now know about metals and nonmetals, answer these questions. Then, classify the following unknown element as a metal or a nonmetal and explain your reasoning. • Unknown element: nonconductive, brittle, and nonreactive to oxygen.

  19. Chem To Go (CTG) Questions 1-6 p 66

  20. Inquiring Further (IF) • Missed lab? Complete Inquiring further on page 67…. • If you did do the lab, you can still complete this “IF” for extra credit

  21. Home work • Watch the videos on physical and chemical properties and create a T-chart to show the differences between the two. • Take down notes in your own format from the power points.(3 PPoints).
